Originally published in 1992, Giant Lizards is a bestselling reference held in high regard within every level of the herp hobby for its authoritative and thorough coverage of lizard biology. Now in a completely revised and expanded volume, Giant Lizards features all newly written information by an expert on monitors and other large lizards (defined as those reaching over 3 feet in length) and it covers over 90 species. Lizard profiles range from the relatively affordable to the extremely expensive, and from those commonly kept as pets to those critically endangered and unobtainable. Species include iguanas (including green iguanas), rock iguanas, Galapagos Island iguanas, tegus, sail-fin lizards, Gila monsters, beaded lizards, water dragons, monitors (including savannah, water, and Nile monitors plus Komodo dragons), and more. Giant Lizards provides complete coverage of essential care subjects like feeding, housing, breeding, and health care. For the more scientifically minded reader, it includes sections o

Brat, a really big dinosaur comes to stay. The other dinosaurs found his differences annoying, but when trouble comes, they realized being different can be a blessing. (I call dinosaur giant lizards) Millions of years ago, long before there were any people, there were dinosaurs. Dinosaurs were one of several kinds of prehistoric reptiles that lived during the Mesozoic era, the "Age of Reptiles." They dominated the Earth for over 165 million years during the Mesozoic era, mysteriously they went extinct; paleontologists study their fossil remains to learn about the amazing prehistoric world of dinosaurs. The largest dinosaurs were over 100 feet (30 m) long and up to 50 feet (15 m) tall the smallest dinosaurs, were about the size of a chicken. Most dinosaurs were in-between. There were lots of different kinds of dinosaurs that lived at different times. Some were armor-plated; some had horns, crests, spikes, or frills. Some had thick, bumpy skin, and some even had feathers.

What caused their extinction remains a mystery, and one that makes an intriguing conclusion to this portrait of a true dragon of the past.

The Monitor Lizard is large; adults can grow up to 7 feet in length. A vicious predator that will eat anything it can fit into its mouth. Native to Africa, the Monitor Lizard has successfully established a new home in Florida, disrupting an already delicate ecosystem.

"Texas offers the opportunity to observe lizard diversity like no other part of the country," writes Laurie J. Vitt in the foreword to Texas Lizards. From the moist eastern Piney Woods to the western deserts, lizards can be found in every part of Texas. The state has forty-five native and six naturalized species of lizards, almost half of the 115 species that live in the continental United States. Yet Texas lizards have not received full coverage in regional field guides, and no other guide dedicated solely to the state's lizards has ever been published. Texas Lizards is a complete identification guide to all fifty-one native and established exotic lizard species. It offers detailed species accounts, range maps, and excellent color photographs (including regional, gender, and age variations for many species) to aid field identification. The authors, two of the state's most knowledgeable herpetologists, open the book with a broad overview of lizard natural history, conservation biology, observation, and captive maintenance before providing a key to Texas lizards and accounts of the various lizard families and species. Appendices list species of questionable occurrence in Texas and nonestablished exotic species. Informational resources on Texas lizards, a map of Texas counties, a glossary, a bibliography, and indexes of common and scientific names round out the volume.

Monitor lizards (genus Varanus) have attracted a great deal of interest--these large and impressive lizards are often the centerpiece of reptile house exhibits. Monitors tend to be fairly wary and difficult to observe--therefore they are not particularly tractable research subjects, but they have nevertheless received an extraordinary amount of attention from devoted students.Varanoid Lizards of the World is a comprehensive account of virtually everything important that is known about monitor lizards, beginning with detailed species accounts and proceeding to various modern comparative analyses. Where possible, people who have had detailed field experience with a particular species have assembled species accounts. In the process of reporting what is known, we also identify what remains to be learned about these lizards. We hope to establish a prototype showing how such a diverse monophyletic group can be exploited both to identify and to understand the actual course of evolution. As such, this effort becomes a protocol for future workers to follow for other groups of closely-related species.

Describes the physical characteristics and behavior of giant lizards such as the iguana and the komodo dragon.

Outlining more than 1500 statistically significant associations extracted from a data matrix composed of more than 300 conditions tabulated—to the extent known—for all 6528 species of lizards, Lizards of the World will be the go-to source for the next generation of reptile ecologists, as well as herpetology students and serious herpetoculturists.
